The Bokanjac–Poličnik system, as a complex set of mutually interrelated Dinaric karst catchments and sub-catchments, is a highly vulnerable and limited groundwater source for the wider Zadar area in northern Dalmatia, Croatia. Based on hydrogeological, hydrochemical, and hydrological research, including the prediction of groundwater discharge by the end of the twenty-first century, a complex study was performed with the following main aims: (1) groundwater protection in the present state, (2) assessment of future groundwater protection, and (3) prediction of drinking water availability and quality under the predicted climate change conditions. Long-term prediction of changes in groundwater quantity, as well as investigations of trends in groundwater quality, will allow us to protect this essential natural resource with respect to possible negative trends. The results showed that a significant decrease in the quantity of available groundwater is possible and that extraction will have to be well planned because any decrease in the groundwater pressure in this area will cause a further decrease in quality, especially regarding the possibility of seawater intrusions into the aquifer. The results of this study were incorporated in sanitary protection zones.

气候变化对沿海岩溶亚得里亚海地区地下水资源的影响：以迪纳里克喀斯特为例

Bokanjac–Poličnik系统是一组相互关联的复杂的Dinaric喀斯特集水区和子集水区，是克罗地亚北达尔马提亚较宽的Zadar地区的高度脆弱和有限的地下水源。基于水文地质，水化学和水文研究，包括到21世纪末的地下水排放预测，进行了一项复杂的研究，其主要目标如下：（1）当前的地下水保护，（2）评估未来的地下水保护，以及（3）在预测的气候变化条件下预测饮用水的供应量和质量。长期预测地下水量的变化以及调查地下水质量的趋势，将使我们能够就可能的负面趋势保护这一必不可少的自然资源。结果表明，可用地下水的数量可能会大大减少，并且必须精心计划开采，因为该地区地下水压力的任何降低都会导致质量的进一步降低，尤其是在海水入侵的可能性方面含水层。这项研究的结果被纳入了卫生保护区。
